tdf#123476 filter: try to detect 0-byte files based on extension
A 0-byte ("empty") pptx file is obviously junk input, so it's not
surprising if the catch-all generic_Text filter is chosen to open it in
Writer at the end.
But we can do better: if we really get an empty file URL with an
extension we can recognize, that we can fake the filter type / filter
name, so the empty "presentation" opens in Impress, and also a re-save
works as expected.
This builds on top of commit 8a201be240b6d408d15166be7ffc576b9e123634
(fdo#68903 Import .tsv and .xls plain text files in Calc by default,
2013-10-27), just the new way works for all supported file extensions
and also with filters which would not handle empty input (e.g. pptx
refuses the import if the ZIP storage is broken).
